Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rear vehicle body structure of an automobile configured to store a spare tire on an upper portion of a rear floor panel, for example.

(Prior Art) Conventionally, as a rear vehicle body structure of the above-mentioned example, there is a structure described in Japanese Utility Model Laid-Open No. 61-154166.

That is, in a convertible type vehicle, a spare tire storage section communicating with the rear luggage compartment is provided above the rear floor panel, the storage section is covered with a storage housing, and the trunk lid is opened to replace the spare tire in the spare tire storage section. It is a rear vehicle body structure configured to be taken out.

However, in the above-described conventional structure, since the storage housing having a substantially L-shaped cross section is arranged above the rear floor panel, there is a problem that the rear body structure cannot be strengthened and the rigidity cannot be increased.

(Purpose of the Invention) The present invention is capable of strengthening the rear body structure and increasing rigidity by reinforcing the rear vehicle body with a mount member, supporting a spare tire on the mount member, and deadening the lower part of the spare tire. An object of the present invention is to provide a rear body structure of an automobile capable of effectively using space to store articles such as tool bags.

(Structure of the Invention) The present invention provides a front cross member and a rear cross member that extend in the vehicle width direction at a predetermined interval on the upper surface of a rear floor panel, and mounts in the front-rear direction that connects these front and rear cross members. A rear vehicle body structure of an automobile, in which a member is provided, a spare tire support portion is formed above the mount member, and a recess for accommodating articles is formed in the mount member.

(Effect of the Invention) According to this invention, since the mount member is stretched between the front cross member and the rear cross member,
With this mount member, the rear vehicle body can be reinforced, and the rear body structure can be strengthened and the rigidity can be increased.

Further, since the spare tire support portion is formed above the mount member, the spare tire mounted on the mount member can be supported by the support portion, and the formation of the recessed portion is also possible. Thus, the dead space under the spare tire can be effectively used to store an article such as a tool bag.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

The drawings show the rear body structure of an automobile. In FIGS. 1 to 3, in an open-top type automobile, a so-called open car 1, rear side frames 3 and 3 are arranged inside left and right side sills 2 and 2 extending in the front-rear direction. A rear floor panel 4 is provided between the lower parts of the left and right rear side frames 3, 3.

As shown in FIGS. 3 and 4, the rear floor panel 4 has a predetermined step in which the front portion is low and the rear portion is high, and the front end portion of the rear floor panel 4 has an inverted L-shaped cross section extending in the vehicle width direction. The extension panel 5 is joined, the front floor panel 6 is joined to the lower front end of the extension panel 5, and the tunnel portion 7 projecting upward is formed in the substantially central portion of the front floor panel 6.

A front lower cross member 8 extending in the vehicle width direction is provided between the front end of the rear floor panel 4 and the extension panel 5, and a closed cross section 9 is provided between the cross member 8 and the extension panel 5. Is formed.

Further, in the upper part of the front lower cross member 8 described above, between the front end of the rear floor panel 4 described above and the front lower cross member 8, a front upper cross member 10 having a substantially gate-shaped cross section extending in the vehicle width direction. This cross member 1
A closed cross section 11 is formed between 0 and the lower cross member 8.

A flat gate-shaped rear cross member 12 is arranged in the vehicle width direction on the rear upper surface of the rear floor panel 4 at a position spaced apart from the front cross members 8 and 10 by a predetermined distance. A closed cross section 13 is formed between the rear cross member 12 and the above-mentioned rear floor panel 4.

Corresponding to the rear cross member 12 described above, a lower cross member 14 is arranged on the lower surface of the rear floor panel 4 in the vehicle width direction, and between the lower cross member 14 and the lower surface of the rear floor panel 4 described above. Also forms a closed cross section 15.

By the way, a mount member 16 that connects the front upper cross member 10 and the rear cross member 12 and extends in the front-rear direction is provided.

The mount member 16 includes left and right side plates 17 and 18,
A bottom plate 19 that connects the bottoms of the side plates 17 and 18,
The left and right side plates 17 and 18 are connected to the upper half of the rear half thereof, and a recess 21 capable of accommodating articles is formed between the plates 17, 18 and 19, and a tool bag 22 is provided in the recess 21. It is configured to store.

Here, the front end bent portions 17a, 1 of the left and right side plates 17, 18
8a and the front end bent portion 19a of the bottom plate 19 are joined to the rear end surface of the front upper cross member 10 as shown in FIGS. 3 and 4.

The curved bent portions 17b and 18b integrally formed at the rear ends of the left and right side plates 17 and 18 are joined to the curved intermediate portion 4a of the rear floor panel 4.

Furthermore, the above-mentioned top plate 20 has its left and right side edges 20a, 20a.
Is joined to the upper end bent portions 17c and 18c of the side plates 17 and 18, and is integrally formed on the front portion of the top plate 20.
3, 23 are joined to the inner side surfaces of the side plates 17, 18 described above.

Furthermore, the joint flange 24 integrally formed at the rear end of the top plate 20 is joined to the upper surface of the rear cross member 12 described above.

A substantially gate-shaped spare tire support bracket 25 is erected and fixed on the upper surface of the top plate 20 of the mount member 16 thus formed, and the top surface 2 of the bracket 25 is fixed.
Two tire mounting portions 26 and 27 are formed on 5a.

A puncture tire 28 is attached to the tire mounting portion 26 on the front side.
The rear tire mounting portions 27 are configured to respectively support the temporary spare tires 29.

On the other hand, as shown in FIGS. 2 and 3, the rear end tongue pieces 30 and 30 are connected to the upper end bent portions 17 of the left and right side plates 17 and 18, respectively.
Rule box cover 31 to be locked to the lower surfaces of c and 18c
The tool box cover 31 is provided with a butterfly bolt 32.
Is detachably attached to the upper surface of the front upper cross member 10 described above.

Incidentally, 33 in FIGS. 2 and 5 is a suspension tower, 34
Is a tire house.

The rear body structure of the open car 1 configured in this way is
Since the mount member 16 extending in the front-rear direction is provided between the front upper cross member 10 and the rear cross member 12, the rear vehicle body can be reinforced by the mount member 16, so that the rear body structure is reinforced and the rigidity is increased. There is an effect that can be improved.

Further, since the spare tire supporting bracket 25 is provided above the mount member 16, one of the puncture tire 28 and the temporary spare tire 29 mounted on the mount member 16 is attached to the bracket 25 and the tightening bolt ( Not only can it be supported by a tool (not shown), but the formation of the above-mentioned recess 21 has an effect that the dead space under the spare tire can be effectively used to store the tool bag 22 and the like.

When storing the tool bag 22 described above, for example, if the temporary spare tire 29 and the tool box cover 31 are removed from the vehicle compartment, the tool bag 22 can be stored in the recess 21 of the mount member 16.

In the correspondence between the configuration of the present invention and the above-described embodiment, the front cross member of the present invention corresponds to the front upper cross member 10 of the embodiment, and so on. Bracket 2
5, the spare tire corresponds to the temporary spare tire 29, and the article corresponds to the tool back 22, but the present invention is not limited to the configuration of the above-described embodiment.
